Custom Monochrome Aluminum PCB (XXA-2509-7W) – A Client Collaboration Story

A custom monochrome aluminum PCB project (XXA-2509-7W) based on a client's physical sample. We produced 100 pieces with a proactive sample strategy, offered 2700K/3000K options, and adapted to a design change — achieving high client satisfaction.

Project Behind-the-Scenes

6 min read • By Elisa

We had the pleasure of working closely with Alex on a custom project in 2025, resulting in a highly satisfactory outcome. The task involved creating a specific monochrome aluminum round plate, designated as the XXA-2509-7W model.

Our goal was precise: to produce a 1:1 replica based on a physical sample Alex provided.


The Initial Steps: Sample Confirmation and Planning

Once we received Alex’s sample, the next step was to confirm the design and proceed with production. Alex requested a full production run of 100 pieces.

To streamline the process and ensure Alex’s complete satisfaction, I suggested a proactive approach: producing the initial free sample 2pcs in advance, but placing the total 100pcs order together.

This strategy offered key advantages:

Advantage

Why It Matters

Consistent quality

Manufacturing the bulk order immediately after confirming the first sample ensured superior consistency throughout the entire batch, directly aligning it with the original sample specifications.

Time efficiency

Eliminated the delay between sample approval and bulk production.

Cost-effective

Reduced administrative overhead and potential for duplicate setup costs.

Alex agreed, and we moved forward with this plan. For the new production sample, we even offered flexibility by creating versions in two different color temperatures: 2700K (warm white) and 3000K (soft white) , catering to potential preferences.


Adapting to New Requirements

After receiving the two new samples, Alex provided a valuable refinement for the bulk order. They requested a modification to the JST female connector: the plastic shell should be removed, leaving only the metal pin exposed.

This was a straightforward adjustment that we readily incorporated into the production plan for the remaining units.

Change Request

Our Response

Remove JST plastic shell, expose metal pin

Immediately incorporated into production plan for all remaining units


Successful Completion and Positive Feedback

Following the implementation of this small change, we successfully completed the entire bulk order of 100 custom XXA-2509-7W aluminum plates.

We are delighted to report that Alex was extremely pleased with the final product and the overall service.

Receiving positive feedback like this is always the best reward and confirms our commitment to quality and customer collaboration.

We look forward to working with Alex again on future projects!
